The Skymach X718 Heavy-Duty Bed Type Milling Machine is engineered for large-envelope machining, multi-ton mold base squaring, and heavy industrial milling tasks. Combining a monolithic fixed-bed foundation with an expansive 2800 x 500 mm precision ground table, the X718 offers an exceptional 2500 mm longitudinal travel and 1020 mm cross travel, handling heavy workpieces up to 5,000 kg with zero table overhang deflection. Driven by a 7.5 kW heavy geared motor through a 7:24 ISO 50 spindle, it delivers immense cutting torque across 12 speed steps (36 - 1340 RPM).
Fixed-Bed Rigidity for 5,000 kg Workpieces
- Zero Table Cantilever Deflection: The heavy worktable rests directly on wide, induction-hardened bedways across its full 2500 mm travel range, eliminating the sagging and angular errors inherent to conventional knee-type milling machines.
- Expansive Machining Envelope: With 2500 mm of X-axis travel, 1020 mm of Y-axis cross travel, and 4 heavy 20 mm T-slots, the table easily secures oversized plate stock, multiple clamping vices, and long structural weldments.
- Deep 900 mm Throat Clearance: A generous 900 mm distance from the spindle centerline to the column guideway allows large-diameter milling heads and deep-cavity tooling to reach inner contours without interference.
High-Torque Geared Drive & Motorized Feeds
- High-Rigidity ISO 50 Spindle: Built with oversized precision bearings and standard ISO 50 taper with dual driving keys, delivering robust metal removal rates with large face milling cutters.
- 12-Speed High-Torque Gearbox: Mechanical multi-step transmission delivers maximum torque at low RPM (36 - 1340 RPM), providing stable, chatter-free performance when cutting high-tensile alloy steels, titanium, and cast irons.
- Motorized Feeds & Rapid Traverse: Complete with variable working feeds (22.4 - 560 mm/min table, 11.2 - 280 mm/min Z-axis) and rapid traverse motors (1650 mm/min table, 825 mm/min Z-axis) for reduced non-cutting cycle times.

Frequently Asked Questions
What is the warranty period for your machines?
We offer a standard 12-month warranty on all our CNC machines, covering the spindle assembly, ball screws, linear guides, CNC controller, and servo drive motors. Extended warranties and customized service plans are available upon request.
Do you provide overseas installation and training?
Yes. Our engineers are available for overseas dispatch to assist with machine installation, commissioning, and comprehensive operator training at your facility. Every machine also ships with English manuals, circuit diagrams, and video setup guides.
What is the typical lead time for an order?
Standard catalog machines ship within 30 days. Custom configurations — such as oversized spindle bores, extended bed lengths, or integrated 4th-axis rotary tables — typically ship within 60 days.
How do you handle spare parts requests?
We maintain a comprehensive inventory of standard spare parts. Genuine replacement components are dispatched via international express (DHL/FedEx) within 48 hours, ensuring minimal downtime for your production line.
